IMPROVED RAKING ATTACHMENT FOR HARVESTERS.

Specification forming part of Letters Patent No. 17,696. dated June 30, 1357.

i 0 all whom it 'may concern Be it known that I, JOHN MCINTOSH, of Geneva, in the county of Kane and State of Illinois, have invented a new and Improved Baking Attachment for Harvesters; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to theannexed drawings, making a part of this specification, in which- Figure l is an end viewot' myimprovement. Fig. 2 is a longitudinal vertical section of the same, the plane of section passing through the center. Fig. 3 is a plan `or top view of the same.

Similar letters of reference indicate corresponding parts in the several gures.

This invention has for its object the discharging of the cut grain from the platform in sheaves or gavels, the parts being so arranged as to operate automatically.

The invention consists in the peculiar mode of withdrawing and releasing the sliding or reciprocating dischargingplate when the same is arranged to operate in connection with an endless apron, as will be hereinafterfully shown and described.

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A Al represent two horizontal and parallel bars, the outer ends of which have'uprightsa a attached. The inner end of the bar A also has an upright, b, attached.

Between the uprights a a, and at their upper ends, a roller, c, is placed, and two rollers, d d, are placed between the lower ends or parts ot' said uprights. A roller, e, is also placed between the inner ends of the bars A A. All of the rollers are shown clearly in Fig. 2.

B is an endless apron, which passes around said rollers, also shown clearly in Fig. 2.

Between the two barsAA, and underneath the apron B, a plate, C, is tted. This plate is equal in width to the space between the bars, and the sides or edges of the plate tit or work in grooves in the inner sides of the bars A A. One side ofthe plate C has a projection, e', attached, and this projection works through a slot in the bar A.

A spiral spring, f, which is attached to the outer side ot' the bar A', is connected to the projection e.

This springfhas a tendency to keep the plate C back underneath the apron B. The outer end of the plate G has two slots,

g g, cut through it longitudinally for a short distance, and projections h, attached to a bar, t, fit in these slots. (See Fig. 1.)

The projections It merely serve as guides to the plate O.

The outer end ot' the plate O has a cord or chain,j, attached. This cord or chain passes around a pulley, k, which is itted in the outer or lower end of a swinging bar, I, attached to the outer end ofthe bar A, and the end of the cord is attached to a projection, m, on a huh or boss, a, of the axle D of the main wheel E. The axle D is fitted in a frame, F, which is attached to the bar A. The outer side of the projection m, which is attached to the hub or boss n, is beveled, as shown plainly at o in Fig. 3.

The endless apron B is driven by a cord, p, which passes around a pulley, q, attached to one side ot' the driving or main wheel E, said cord also passing around a pulley, r, at one end 0f the roller c, and around guide-rollers s at the upper ends of the upright b.

The operation is as follows: As the machine A is drawn along the cut grain falls upon the apron B, which is, in fact, the platform of the harvester. The apron B moves with a continuous motion in the direction indicated by the arrow, and a reciprocating motion is giveni the plate C as follows: The plate C is drawn out in consequence of the cordj being'wound around the hub or boss n, and said cord is cast ottl from the hub or boss at every revolution of the hub or boss by means of the projection m, the inclined side o performing the work every time it reaches a vertical position. When the cord j is cast ott' from the hub or boss a the plate G is forced back underneath the apron B by the spring j'. While the plate Gis being drawn outward the cut grain is deposited upon it by theapron B,and as said plateis forced back by the spring fthe grain upon it is deposited on the ground. Thus it will be seen that at every revolution of the wheel E a gavel is deposited on the ground.

The above invention is extremely simple, may be constructed and applied at a small cost, and there are no parts liable to get out of repair. The device works automatically, no attendant being required besides the driver of the team. v

I am aware that endless aprons and sliding plates have been frequently employed on harvesters for the purpose 0f discharging the cut grain from the machine, and I therefore do not claim the employment or use of such separately or in themselves considered; but,

Having thus described my invention, what I elaim as new, and desire to secure by Letters Patent, is-

The peculiar method above described for withdrawing and releasing the sliding plate U when the same is used in combination with the endless belt B, in the manner and for the purpose herein set forth.

JOHN MCINTOSH.
